Hey guys, I need help with my 2007 Honda Odyssey trouble code P0175, fuel system too rich. I already replaced the bank 1& 2 oxygen sensors. I also clean the egr valve, I also cleaned the air flow sensor. The car is runing really well in high speed the problem is when I got in the traffic the car is vibrating terrible. The engine mount is good. I went to auto zone for my car to be scanned the code that I got is P0175 fuel system too rich bank2. Probable cause fuel system concern, ignition system concern, MAF sensor faulty, H02S/AF heated oxygen sensor /air-fuel ratio sensor fault. Also sometimes I had hard starting vehicle.

1. You may need a valve lash adjustment. Notice the valves making more noise than usual? Should be done every 60-100K miles anyways.

2. Bad injector(s)

3. Bad fuel pressure regulator

I forgot also to mention. I have display sign on my dash. Check fuel cap. Is this related to this problem?
